我是XSLT的新手，我正在尝试将XML转换为固定宽度的文件。

我用过这个例子：
XML to Fixed width text file with xsl style sheet
期望的输出：

ITEM3 20040201 PK181015 Leased Lines

FOOTER HARD-CODED STUFf
这是我目前使用的，但它没有生成任何文件，我不知道原因：

答案 0 :(得分：1)
您有几个问题：
1.您正在使用前缀“ns2”withput将其绑定到命名空间。将其添加到样式表声明中：
xmlns:ns2="FPPD2.srdl"
2.您的主模板与/根节点匹配。从这个背景来看，
指令：
<xsl:apply-templates select="/ns2:Detail_2_1/ns2:Detail_2_1_Group_Collection/ns2:Item"/>
不会选择任何内容，因为Detail_2_1不是根节点的子节点。请尝试改为：
<xsl:apply-templates select="ns2:Report/ns2:Detail_2_1/ns2:Detail_2_1_Group_Collection/ns2:Item"/>
另请注意，在匹配模式中，node() 不匹配属性 - 因此将忽略您的格式设置模板以及复制文本值的内置模板规则因此，将被调用。
- 如何在第一行放置一些属性（例如DocumentNumber），其中一些属性（例如amount_TOTAL） 在txt文件的最后一行;
类似的东西：
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns2="FPPD2.srdl">
<xsl:output method="text"/>
<xsl:variable name="some_spaces" select="' '" />
<xsl:template match="/ns2:Report">
<xsl:text>HEADER000001 </xsl:text>
<xsl:call-template name="pad">
<xsl:with-param name="text" select="@DocumentNumber"/>
<xsl:with-param name="width" select="15"/>
</xsl:call-template>
<!-- more calls to complete the header -->
<xsl:text> </xsl:text>
<xsl:apply-templates select="ns2:Detail_2_1/ns2:Detail_2_1_Group_Collection/ns2:Item"/>
<xsl:text> FOOTER </xsl:text>
<xsl:call-template name="pad">
<xsl:with-param name="text" select="@amount_TOTAL"/>
<xsl:with-param name="width" select="10"/>
</xsl:call-template>
<!-- more calls to complete the footer -->
</xsl:template>
<xsl:template match="ns2:Item">
<!-- ... -->
</xsl:template>
<xsl:template name="pad">
<xsl:param name="text" />
<xsl:param name="width" />
<xsl:value-of select="substring(concat($text, $some_spaces), 1, $width+1)"/>
<!-- why +1 ? -->
</xsl:template>
</xsl:stylesheet>
